Relationships among vegetation classes along the upstream-downstream elevation gradient and along individual transects are presented in Figure 5-7 and Table 5-5. Median absolute elevations of vegetation classes differed by about 10 to 20 feet from the upper to lower end of the sampled river reach. At transects where they occurred, popash and oak/popash classes were typically the lowest vegetation classes, with median elevations less than 8 feet above the river channel bottom (Table 5-5). Median elevations of hickory/oak and oak/cabbage palm classes were intermediate, ranging from 5.5 to 13.2 feet above the river bottom. The oak mix and pine/oak classes occurred at the highest elevations as compared with the other classes. Median elevations of the oak mix class, which included the greatest number of upland species, as well as the greatest number of species overall, ranged from 12.3 to 16.5 feet above the river bottom. Median elevations in the pine/oak class ranged from 10.7 to 19.2 feet above the bottom of the river channel. 5-12

Downstream Upstream The soils along the Braden River are dominated by sand, limestone, and clay rather than by organic materials (USDA/SCS 1989). Hydric soil conditions along transects occurred at lower median elevations when compared with non-hydric (upland) soils (Wilcoxon Sign Rank; S = 18; p < 0.01). Furthermore, hydric, muck, and saturated soils conditions were characterized by lower elevations 5-13
